The early disabling of irrelevant arch extensions is no longer
required, and removing it makes dependencies involving these
work as expected.

Merge find_near_mvs and mv bitstream decoding: don't do prediction steps
until absolutely necessary.

s->windowed_samples will always have a range of [-32767,32767] due to the
window function, so the return value from log2_tab() will always be in the
range [0,14].

This code will be later split out into a function which takes a 'size'
argument, so I'm keeping the name 'sizeX' here.

Only trivial splits are done here -- i.e. copy/paste + reindent +

Instead of returning an error when bytes are left over, just return
the number of actually used bytes as other decoders do.
Instead add a special case so an error will be returned when none
of the data looks valid to avoid making debugging a pain.

The function return type is void, so a return statement with an

that the encoder supports the specified sample format. Error out if it doesn't.
